A crypto debit card is exactly like a regular payment card, except that you have the option to load it with crypto instead of fiat. In most cases the provider offers an app that holds both crypto and fiat currencies like Euros or US Dollars. When users want to make a purchase in a store (or online ) they can convert their funds into fiat within the app and spend those funds instantly with their crypto debit card.

Crypto rewards are attractive if you use it as your primary card and start earning rewards on all your spendings. It’s important that they offer fiat top-ups by card so that you can transfer funds from your main bank account and spend your fiat instead of spending crypto. If you have to sell crypto the money you lose on the conversion might cancel out the crypto rewards.

Most crypto card providers make money when you are selling crypto. They also receive a small commission from Visa/Mastercard when a user makes a purchase in-store. Some offer it only to get better customer retention.

A crypto card makes sense if you need quick access to funds but you have a lot of your wealth in crypto. With a crypto card you can instantly make a purchase using your crypto whereas if you would withdraw the funds to your bank account it would take 2-3 days until you can spend it.
